You may have noticed that for some time, downloaded videos from Vimeo (or from sites hosting their videos on Vimeo) do not have audio.
This is due a change in their streaming technology and they now stream the audio and video parts of the media separately, as YouTube have been doing for several years.
The Video DownloadHelper workaround is the same as with YouTube: use an external video converter to aggregate audio and video streams into a single audio+video file that can be used by your video player.
We are aware of the inconvenience of having to install an external application, but there is no easy alternative here. Note that once the converter is installed, the process is totally transparent and you end up with a fully playable video without any special action.
If you want to avoid using the converter, you can still use Video DownloadHelper to download separately the two streams (but you will have to find a way to play them together). For doing so, open DownloadHelper settings > More > Chunked streaming, check Advanced. In section DASH streaming, parameter When DASH contains both audio and video lets you choose which stream(s) you want to download. Default is Aggregate audio and video, which implies using the converter but you can change it to choose audio or video only.
A number of YouTube videos are streamed not only in ADP mode (audio and video in separate streams) but each of those streams in DASH mode (plenty of small segments that need download and rework to create a playable media). Previously, Video DownloadHelper ignored those videos, causing a No media found message to be displayed. With version 6.2.0, you are now offered to download those videos in several quality variants.
HLS-streamed videos have been supported since version 5.5.0 but some servers use encryption on those streams, causing Video DownloadHelper to generate a useless 48 bytes file. This new version supports encrypted HLS.
A number of users complained about not having audio when playing HLS videos using Windows Media Player. This is now fixed and you don't have to use alternative players to hear those videos.
In some cases, HLS captures lead to a file containing only audio. This was due to a bug that has been fixed in this version.
Users with very poor networking conditions like an Internet connection going up and down had a hard time downloading videos, particularly big ones. The new version fixes an issue with chunked downloads not using retries properly, and add a configurable delay between retries.
Version 6.2.0 also fixes an issue with pages containing many videos (like a video-oriented tumblr page). If requesting some downloads and scrolling down to make new videos to be detected, you could lose control of the downloads.

being encrypted. Learn more about the Masked Download feature.
You can now use the multi-formats video player that comes with the converter thanks to the new Play action.
Better F4F capture support: you can now choose between several quality variants when available on the server.
Videos streamed over the chunked protocols HLS (MPEG-TS/MP2T, on sites like Dailymotion and many live streaming sites) and DASH (M4F used on sites like Vimeo) can now be downloaded without the need for the converter. Previous 5.4.x versions had a basic support for those streams, but it was inconvenient (you had to keep the video running) and the converter had to be used to finalize the download to a proper video file. This new version even offer in most cases the choice between several quality variants.
The old list of supported sites (which were not maintained anymore) is back to life. All the listed 1000+ video web sites are alive and are DownloadHelper-compatible. New sites are added weekly. Those lists are hosted on the downloadhelper.net website and no longer managed by the addon.
A long-time request from users with a low quality network connection: automatic download retries. If the download fails in a recoverable way, the add-on tries to resume the download from where it stops. The number of retries before giving up is configurable.
Add-on settings are now managed from with a tab and no longer an add-on panel.
The DownloadHelper icon is now usable from the Firefox options panel.
An option has been added to switch to the tab owning a particular video entry in the panel.
Video entries with long titles can now have the ellipsis (…) at right, left or display over several lines, based on the settings).
Fixes from previous 5.4.2 version:
- Fixed filename overwriting on simultaneous captures
- Fixed YouTube ADP variants that could generate aggregation errors
- Fixed gallery downloads with spaces in file names
- Fixed canceling download from Firefox manager cancels entry download in add-on
- Fixed wrong video window ownership when popup is launched at video start
- Fixed download list showing chunks on YouTube when smartnaming default was set to header/url or obfuscated
- fix for Dailymotion change on October 11th
- added zh-TW (traditional Chinese) locale
This capture method is used in two new features:
- Browsing session capture: an easy way to make web sites demo videos. The add-on captures the visible part of a browser window and optionally, is able to highlight the mouse.
- Applet capture: the add-on analyzes the loaded page to detect Flash and video regions big enough to be considered as capturable content and creates new entries in the detected hits list. Passing the mouse over those entries highlights the related region in the page so you know what you are about to capture.
Other minor fixes and additions:
- optionally use browser's default download directory instead of VDH specific one
- optionally display VDH controls from the Tools menu
- optionally allows prefixing gallery captured files with incremental number
- MP2T capture can now be configured from the settings
- conversion output profiles can now be configured from the settings
- if converter is not installed, place ADP variants detected from the network at the bottom of the list
- MP2T Streaming capture: record some chunked streamed videos
- Twitter Periscope Auto-recorder: auto-capture Periscope live streams
- Toolbar button modes: main toolbar button in now optional
- Optional main panel compact display mode
- Improved smartnaming including obfuscated file names
- New localizations

- Many fixes

Enjoy your new Video DownloadHelper !
Fixed a number of issues with YouTube
After some changes in YouTube on August 6th, a number of users reported that all downloads were failing. This was caused by a a Youtube-generated cookie. The workaround consisting of clearing the cookies before downloading was not very convenient. This addon version takes care of that issue.
Earlier this year, some other changes at YouTube caused the FLV videos downloaded through the 'network' method to have a fixed 1.7MB size and being unplayable. This is now taken care of.
